GPR removal from beyond the apical foramen using TFRK-S and TFRK-GPR followed by XP-endo Finisher

TFRK-S was used to create a space for the placement of TFRK-GPR which manually removed gutta-percha fillings (GPs) from the C-shaped canal. But the gutta-percha residue was found remaining beyond the apical foramen. The attempts to get the remaining GPs out failed with TFRK-GPR. Then chloroform was injected into the canal and the XP-Finisher (XPF) was spinned at 2500 rpm beyond the apical foramen with a short up/down stroke. The GP residue was successfully removed from the periapical tissues. 樋状根の根管にTFRK-Sを使いTFRK-GPRの挿入スペースをつくり、根管内のGPをTFRK-GPRで除去した。しかし顕微鏡下でみると根尖孔外にGPが存在しているのが確認できた。さらにTFRK-GPRで除去を試みるも上手くいかなったので、クロロホルムを根管内に注入しXPエンドフィニッシャーを2500rpmで根尖孔外で上下動しながら回転させたところ、根尖孔外のGPを除去することができた。
